Rommelpot (Medieval folk instrument, makes rumbling noise)
umuD (a "mutator" gene)
dinB (another "mutator" gene)
So far, all these names have been rejected by the Real Doctor. I'm the first to admit that I don't have the most normal history for naming beasts--I or my family have had "Nothing" the kangaroo rat, "Stupid" the Carolina anole, "Fuzzybutt Turdflinger" the chinchilla, and Opal (named after a famous mutant). If you have suggestions, please comment.
